Prevalence and diagnostic features of osteoarthrosis of the temporomandibular joint: a review

Abstract

Temporomandibular disorders (TMD) consist of not only the internal derangement of Temporomandibular joint (TMJ) but also areas extrinsic to TMJ. Osteoarthritis is a common degenerative joint disease that manifests as a chronic debilitating disease and occurs due to degradation and loss of articular cartilage. There occur changes in the subchondral bone and other soft tissues. Osteoarthritis is not uncommon in the Temporomandibular joints (TMJs). The etiopathogenesis of osteoarthritis is associated with multiple risk factors. The disease progresses slowly and passes through different phases with periods of remission and ultimately results in the burnout phase. It needs a good understanding of the diagnostic algorithm and that facilitates better management of the disease in the TMJ. The aim of this review article is to highlight and update the prevalence, diagnosis, pathogenesis and general characteristics of TMJ Osteoarthritis.
